Teaching Portfolio


In several years of experience at Universidad Simón Bolívar I held positions from Undergraduate Teaching Assistant to Assistant Professor. I assembled the following portfolio to take stock of my taught courses, describe my teaching approach and give insight about what I have learned along the way.

Currently, I am part of the Electronics and Circuits Department, and my teaching area is oriented towards theoretical and experimental foundations of electronics for data acquisition systems. As responsible of core courses for senior level engineering students, my lessons cover a broad range of subjects – from the electrical translation of physical magnitudes up to their representation and processing in the digital world.

Additionally, I perform as co-instructor of the Spanish version of the MOOC “Learning How to Learn” offered by UC San Diego through Coursera, which offers useful tools to enhance the learning process by means of the latest research in neuroscience and cognitive behavior.

The exciting side of teaching is that after every course offering I discover new things to learn and new areas to improve, so I consider my portfolio – and my personal development – as a constant work-in-progress. More information about my work can be found on:

Teaching Philosophy



The interesting part of science is that it is an endless discovery driven mainly by curiosity and asking the right questions. As Hubble said:

Equipped with his five senses, man explores the universe around him and calls this adventure “Science”.

Despite being in permanent contact with technology, I find nature as the ultimate source of inspiration and fascination. As a famous author once wrote:

The simplest life form holds more secrets than the most advanced supercomputer.

This is the reason of my slight preference towards analog and power electronics – the underlying physical principles ruling our universe will never run out of date.


As a teacher, I am in charge of the construction of a safe environment that allows students discover, learn, and make mistakes. I encourage them to take risks, engage with the course objectives and clarify misunderstandings. In return, I feel grateful when students discover a way to expand my own understanding of the subjects adding their particular contributions.

Since the first day of class, I strongly suggest my students to pay attention to details, especially those related to calling things by their own name. This way, the information flows more efficiently in the classroom, and also with external peers. I advise to take nomenclature seriously, and to express ideas clearly in both written and oral language. I consider communication skills are fundamental to enable human cooperation in large numbers. After all, a team of top-class people is able to accomplish a lot more than a single person.

I am aware that the biggest part of teaching goes beyond the words I could say or write, and this is why I take into account the modeling of attitude. Students learn unconsciously the attitude of teachers towards day to day tasks, and the way we face unexpected situations. Since teaching is a multifactorial activity, it is a challenge to control every aspect of the interaction with every single student; and this is why it is important to have a well defined teaching philosophy as a firm set of beliefs running in the background.


What I Teach ?


Currently, I am in charge of three courses oriented to fourth year students of the electronics engineering career at Universidad Simón Bolívar. Each course is suited for a three-month period that is meticulously scheduled in twelve weeks of activities.

EC3179 – Electronics for Industrial Control and Data Acquisition I

This course is oriented towards the translation of physical variables up to their representation in the digital world, with a focus in analog to digital and digital to analog conversion, sensors, signal processing and an introduction to digital electronics.
